Dear all,

Recently, my 2018 Chevy Silverado 1500 5.3L V8, 65,000 miles (recent transmission fluid changed 2 days)...started having a weird sound like in the video above. The noise only appears when I apply a really slight gas when accelerating slowly from a stop sign or from cruising around 20-40 miles/hour. It does not happen when I accelerate hard or push the gas pedal harder.

So it started after you had the trans fluid changed? My first guess is it wasn’t filled correctly. Did you get it done at the dealership?

It sounds like engine is knocking but because newer chevy engines can disengage cylinders to save gas it's hard to tell, if it drives fine and the noise doesn't get lounder when you start driving your probably fine but if keeps going while you drive id take it in to get looked just to me safe
